Dr Crispin Halsall CChem MRSC

Reader

Research Overview

Crispin is an environmental chemist who has a deep interest in how synthetic organic chemicals behave in the environment. He is particularly interested in assessing and reducing the risks posed by some of these chemicals to both the wider environment and to human health.

He researches the fate of industrial chemicals, pesticides and pharmaceuticals and those factors that affect their longevity in the environment, including in remote regions like the Arctic!

Published research

Crispin has published over 70 peer-reviewed papers on chemical pollutants and their fate. One of his papers, published in 2010, has received over 110 citations and details the environmental fate of endosulfan, an organochlorine pesticide that has subsequently been incorporated into the UNEP Stockholm Convention on Persistent Organic Pollutants.

Funding organisations include:

  • Arctic pollution research: The Natural Environment Research Council (NERC), EU’s 7th Framework Programme - ArcRisk project
  • Pesticide photodegradation: Biotechnology & Biological Sciences Research Council (BBSRC), The British Council
  • Pharmaceuticals in aquatic systems and analytical instrumentation: Engineering & Physical Sciences Research Council (EPSRC), United Utilities and other private sector organisations

Current research projects include:

  • Accumulation of ‘emerging’ chemical contaminants in the snowpack;
  • Analytical determination of antibiotics in aquatic systems and novel degradation/removal processes;
  • Pesticide photo-degradation on crop surfaces;
  • Improving the chemical risk assessment process for policymakers

Listen to Crispin talking about the impact of chemical pollutants on wildlife on Monty Don’s ‘Shared Planet’ series on BBC Radio 4 or read more about this research.

Roles

Within the Lancaster Environment Centre, Crispin currently serves as the postgraduate review panel chair for Environmental Chemistry and helps coordinate the Environmental Chemistry research grouping.

National/international roles include:

  • Member of the Arctic Monitoring Assessment ‘POPs expert group’;
  • Review Panel member of the Research Council of Norway;
  • Recent member of the NERC peer-review college;
  • Member of SETAC’s ‘Friends of the UN’ observer scientist cohort
  • Editorial board member of the journal ‘Toxics’

Teaching

Crispin’s teaching includes:

  • An undergraduate course on Biogeochemical Processes as part of the LEC BSc degree schemes in Earth and Environmental Science and Geography
  • Two highly popular Masters postgraduate courses in Chemical Risk Assessment and Environment Toxicology, that serve as core modules for several of the LEC Masters degrees

Outside interests

When Crispin is not in the department or helping to bring up to two boisterous teenagers he can be found running in the Bowland Fells (Fjell (Nordic) = hill) and is a member of Bowland Fell Runners. Crispin’s tries to compete in at least one category A, super-long fell race each year. Recent notable races that he has run include the Yorkshire Three Peaks, the Duddon Valley and the Ennerdale Horseshoe fell races.
